CLOUD WARS -- Microsoft’s booming $8.5-billion in cloud revenue last quarter has helped it open a decisive lead over Amazon as the world’s leading enterprise cloud provider for the past 12 months, $26.7 billion to $23.4$ billion.

Dynamics 365 revenue expected to hit $1.25 billion for the fiscal year (ending June 30, 2019); and

LinkedIn revenue up 33% to about $1.5 billion.

During his prepared remarks on Microsoft’s earnings call last week, CEO Satya Nadella offered this perspective on the centerpiece of the Microsoft cloud: “Azure is the only hyperscale cloud that extends to the edge across identity, data, application platform and security and management. We introduced 100 new Azure capabilities this quarter alone, focused on both existing workloads like security and new workloads like IoT and Edge AI.”

For AWS, some analysts and media outlets made a big to-do about the fact that the rate of growth for Amazon’s cloud business took a tiny downward turn for the quarter, slipping from 49% to 46%.

I think that’s an overblown detail—if you look at the last several quarters, AWS has consistently achieved the remarkable feat of having its growth rate increase even as it has approached an annualized run rate of $25 billion. Starting with Q4 of 2016, the revenue-growth rate for AWS has been 42%, 42%, 44%, 48%, 49% and most recently 46%.

The very same minor decline in rate of growth occurred at Microsoft as well—its commercial-cloud revenue for the period ending June 30 was 53%, and then for the 3 months ending Sept. 30, that slipped to 47%.

It’s pretty much inevitable that as the cloud businesses of Microsoft and Amazon reach this type of scale--$26.7 billion in revenue for the past 12 months for Microsoft, and $23.4 billion for Amazon—growth rates will eventually decline. But if somebody’s got a problem with 47% growth for $25-billion businesses, then I’d say that person doesn’t have a clue.

For IBM, its cloud business was one of the few bright spots in a largely challenging quarter as it posted $19 billion in cloud revenue for the 12 months ending Sept. 30, with the “as a service” portion of the IBM Cloud racking up $11.4 billion in revenue, up 24%.

But yesterday, IBM took a huge step to scale its cloud business by agreeing to acquire Red Hat for $34 billion, an acquisition that would add about $3 billion to IBM’s annual cloud revenue.

For Microsoft and Amazon, the competition over the next year will center on more than advanced cloud and AI technology as Microsoft continues to hammer on Amazon’s aggressive corporate strategy of jumping into an expanding array of industries and pitting itself as a direct competitor of businesses that might otherwise be viable prospects for AWS.
